Specification of Letters Patent.

Application filed August 28, 1912.

Patented J an. 21, 1913. Serial No. 717,579.

To all whom it may concern:

Be it known that I, HERVEY N. Boys, a citizen of the United States,residing at Rollin, in the county of Lena-wee and State of Michigan,have invented new and useful Improvements in Milk Cooling, Ventilating,and Protecting Devices, of which the following is a specification.

This invention relates to milk cooling, aerating and protecting devicesfor milk cans, and has for an object to provide a device of thischaracter which may be readily applied to a can of any well knownconstruction; one that will effectually fit over the neck or open end ofthe can to protect the contents from insects, animals, foreign matter oroutside elements, and one which will open the interior of the can to theoutside air so as to provide for a perfect circulation of air within thecan and permit the animal heat to quickly pass from the milk.

In the drawing forming a portion of this application, and in which likeletters of reference indicate similar parts in the several views :Figure1 is a vertical section through a can showing the application of theventilating cover therefor. Fig. 2 is a horizontal section on line 22 ofFig. 1 looking in the direction of the arrow. Fig. 3 is an invertedperspective view of the ventilating cover.

The combined protecting cover, aerator and cooler comprises a cap member1 which is preferably in form of an inverted circular tray, beingprovided with a crown 2 and vertical side walls 3. A foraminous member 4is disposed in parallel relation with the crown 2 through the medium ofthe depend ing walls 3. This member has its marginal edge lying inmutual contact with the lower edges of the walls 3 and securely confinedin the annular crimped portion 5 of the latter as shown.

The milk can 6 herein conveniently shown is of the usual well knownconstruction and configuration, being provided with a vertical neck 7whose walls are flared outwardly at 8 and then downwardly at 9 topresent an an nular groove 10 entirely around the neck for a purpose tobe hereinafter explained. The cap member 1 has a diameter which greatlyexceeds the diameter of the neck 1 so that outer portions of theforaminous material 4 extend laterally beyond the neck when the capmember is operativelv centered u on the neck. In this manner theinterior of the can 6 is opened to the outside air to effectually set upa perfect air circulation within the can with a resultant coolin of itscontents as is evident. The central portion 11 of the foraminousmaterial lies in flat contact with the neck and is extended entirelyover the upper end thereof to form a screen to protect the contents ofthe can from insects. With a view to properly centering the cap member 1upon the neck and for holding the latter against accidental displacementtherefrom, I provide arcuate companion neck gripping devices 12 whichare identically constructed and preferably formed of springy wire. Theterminals 13 of the members 12 are soldered or otherwise suitablysecured at 14 to the crimped portion 5 of the cap member and from saidsoldered portion the terminals are offset downwardly as at 15 and thenextended by the guiding portions 16 directly into the arcuateintermediate portions of said grippnig devices. The terminals 13 of thecompaniongripping devices are flared relatvely and spaced sufiicientlyto permit the upper end of the neck of the can to be readily extendedabove the portion 16 and then guided in between the arcuate grippingportions for efl'ective clamping encasement therewith. The oppositeterminals 17 of the gripping devices are arranged in relatively closerelation and preferably soldered or otherwise suitably secured to theportion 5 of the cap member and as shown said terminals are providedwith vertical off-set portions 19 which form stops that engage againstthe peripheral edge of the neck 7 to limit the sliding adjustment of thecap member and to cause the member to be. properly centered upon theneck of the can.

I claim 1. An aerating cover for milk cans comprising a substantiallyinverted tray-shaped cap member having a foraminous base adapted textend acr ss the neck of the can and to also extend latorallvtherebevoud. and vieldable means carried by said member and adap ed toreceive t e neck of he can whereby the member is held secured thereon.

2. An aerating? cover for milk cans comprising a substantially invertedtray-shaped cap member having a foraminous base adapted to extend acrossthe neck of the can an to als extend laterally th rebevond. andyieldable means carried by said member and adapted to receive the neckof the can whereby the member is held secured thereon, and means formingpart of said yieldable means to engage against the neck to center thelatter with relation to said member.

3. An aerating device for milk cans comprising a crown having dependinside walls a foraminous ventilating mem er secured to said side wallselastic means disposed beneath the foraminous member and havingrelatively adjustable gripping portions for receiving the neck of thecan, guiding portions extending from said gripping portions, the saidcrown being slidably adjustable over the neck, and means for limit ingthe sliding adjustment of the crown so as HERVEY N. BOYS.
